Many people often experience this nuisance in their lives – bleeding gums, which mostly occurs in the morning when they are shagging, or can occur when they are eating and find blood on their food; these make many people feel fearful and wonder which part of them has a problem. Broadly speaking, the causes of bleeding gums can be divided into two categories: gum manifestations of systemic diseases, such as leukemia, where the gums have a pronounced tendency to bleed and the gingival margin often oozes blood and is not easily stopped; the other is the manifestation of local inflammation of the periodontium, such as gingivitis and periodontitis, where the gums are red and swollen and bleed easily when touched. For gum bleeding caused by systemic diseases such as leukemia, systemic disorders should be treated first to eliminate the cause of gum bleeding, and the symptoms of gum bleeding will be reduced, then supplemented with local treatment of the oral cavity. The incidence of the above-mentioned cases is low, and what is common in our life is the gum bleeding caused by gingivitis and periodontitis, which is caused by the local stimulation of the gums by plaque and tartar, resulting in the expansion and congestion of capillaries in the connective tissue of the gums, and the rupture and bleeding of capillaries caused by different degrees of stimulation. For gingivitis and periodontitis, the treatment is generally effective after active and effective treatment. Proper shampooing can remove most of the plaque, but not the tartar, which must be removed by an oral surgeon with a special instrument, i.e. scaling – or “scaling” as it is often called. “Scaling can treat most cases of gingivitis and mild periodontitis, but moderate to severe periodontitis requires systematic periodontal treatment. With these treatments, the symptoms of bleeding gums will be greatly improved.
